Since it is a conventional structure, further explanations will be omitted. Each of the two sliding sleeves 25 is positioned on the main rod 21 by rivets or screws; it is also a conventional structure, so no further explanations will be necessary here. In addition, the four support rods 20 are arranged in groups.

The two base members 30 are respectively positioned between the four support rods 20 and are positioned in the axial direction of the respective support rod 20. Each of the base members 30 is formed with a threaded hole A and is pivotally coupled with four pivots 31, and the four pivots 31 are pivotally coupled to the corresponding sliding sleeves 20 respectively, so that the four support rods 20 can be folded and unfolded, with the two base members serving as a center.

The connecting member 40 is a rod, on each end of the connecting member 40 is formed a threaded end a, and the two threaded ends are screwed in the two threaded holes A of the base members 30 respectively. In such a manner, the structure strength of the two base members 30 is improved, and when the two base members 30 and the four support rods 20 are folded or unfolded, the two base members connected in an interactive manner will move in the same direction.

When the ball storage rack of the present invention is unfolded, a basket X can be positioned on it. When the four support rods 20 are folded, each support rod 20 pushes its corresponding pivot 31 to pivotally rotate. Then the pivots 31 will drive the corresponding base members 30 to move towards the axial direction of each support rod 20. The two base members 30 can move in the same direction by the linkage of the connecting member 40, so that the whole rack can be folded, and it can be put in a bag Y after being folded.
